Objectives : This study was conducted to review the research trends in Korean Medicine of pompholyx based on publications in Korea. Methods : Literature published after 2000 were collected using OASIS, NDSL, KISS, and key words searched were "한포진" "발한이상" "pompholyx" "dyshidrotic eczema". Results : 10 case reports and 4 patient studies were selected for study. Conclusions : Korean medicine treatments included acupuncture, pharmacopuncture, venesection therapy, herbal medicine, ointments and carbon arc lamp therapy. The most commonly used diagnostic method for pompholyx was inspection along with pulse diagnosis, abdominal diagnosis, tongue diagnosis, culture test, and KOH smear screening. The most frequently used treatment evaluation method was Likert scale while VAS(Visual Analog Scale) and Visual&Subjective symptoms were each used in 4 studies. Among 29 patients in 14 papers who showed clinical manifestations of pompholyx, there were 15 male patients (52%), 14 female patients (48%), and the male to female ratio showed 1.07:1. Symptoms were improved using Korean Medicine treatments including acupuncture and herbal medicine. Concurrent treatment using special treatments such as pharmacopuncture, jiyang-go, bojungikgi-tang(ex), external applications showed higher treatment effects. Korean medical treatment of pompholyx was effective in all studies, but the lack of numbers of research on Korean medicine of pompholyx was witnessed compared to other diseases such as psoriasis. Also considering the number of patients suffering from pompholyx, further studies should be conducted.

Foresight, a major methodological tool in the STI policy toolbox, has recently featured new directions in methodological development, becoming influenced by progress in information and communication technologies and online tools. However, no overview of these directions has been available so far. Based on a literature review, an interactive workshop, and an international expert survey as well as expert interviews, the research presented here attempts to shed light onto some of the relevant issues by providing a structured overview of recent changes in order to further the debate on the future directions of methodological development in foresight. The paper outlines four clusters of emerging approaches in foresight:Integrated qualitative and quantitative approaches, IT-based and automated foresight, experiential foresight including new forms of communication and interaction such as visualization and gaming, and open and crowd-sourced approaches. The benefits and challenges of the approaches known so far are categorized and summarized, and areas of potential use for each of the clusters in STI contexts are identified.

In recent years, beryllium oxide has been widely utilized in multiple compact nuclear reactors as the neutron moderator, the neutron reflector or the matrix material with dispersed nuclear fuels due to its prominent properties. In the past 70 years, beryllium oxide has been studied extensively, but rarely been systematically organized. This article provides a systematic review of the application history, thermal properties, mechanical properties, corrosion behavior and fabrication methods of beryllium oxide. Data from previous literature are extracted and sorted out, and all of these original data are attached as the supplementary material, so that subsequent researchers can utilize this paper as a database for beryllium oxide research in reactor design or simulation analysis, etc. In addition, this review article also attempts to point out the insufficiency of research on beryllium oxide, and the possible key research areas about beryllium oxide in the future.

Among all hazardous air pollutants, polycyclic aromatic hydrocarbons (PAHs) are more significant owing to their carcinogenic, mutagenic and teratogenic properties. Many researchers worldwide have focused on determining the concentrations of PAHs in ambient air. However, the literature survey reveals that the seriousness of air pollution in Asia in terms of PAHs, compared to the rest of the world. Owing to the importance of PAHs in Asia, this paper reviews the concentrations of PAHs in Asia in recent years. For convenience, this paper describes the concentrations of PAHs in developed Asian countries reported during 2000-2011 as Part-I and in developing Asian countries as Part-II. The first section of this review provides a brief description of the properties, sources of PAHs and the health effects caused by their presence in the atmosphere. The ambient air PAH concentrations in both particle and vapor phases in developed Asian countries are then discussed. This study finds the ambient air concentrations of PAHs in developed Asian countries was higher than the Western countries but was lower than the developing Asian countries. The present review predicts the accurate toxicity due to the presence of PAHs in the atmosphere by calculating the Risk Weighted Concentration (RWC), regardless of the total amount of PAHs. The total data obtained during the literature survey is tabulated and presented as supplementary information to the readers.
